This study was conducted to investigate the antioxidant activity of the extracts of lotus (Nelumbo nuciferaGaertner). The total phenolic contents in leaf, stem, and root were 165, 74, and 30 tannic acid equivalent mg/g of dried extractor fraction respectively. The butanol and ethylacetate fractions of lotus parts showed higher 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical scavenging activity than other fractions. 2,2'-Azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) cationradical scavenging activity also showed the similar result as the DPPH radical scavenging activity. The antioxidative capacityof the ethylacetate fraction was the highest among fractions and its fraction showed higher contents of total polyphenol.
